F(x)=5^x if F(-2) what does this equal

KengaRu [80]

Answer:

$\frac{1}{25}$

Step-by-step explanation:

Using the rule of exponents

$a^{-m}$ = $\frac{1}{a^{m} }$ , hence

f(- 2) = $5^{-2}$ = $\frac{1}{5^{2} }$ = $\frac{1}{25}$

IM SO DUMB I NEED HELP

alexdok [17]

Answer:

$76.0m^2$ (you have to have the .0 since it says to round to the nearest <em>tenth</em>)

Step-by-step explanation:

The formula for the surface area of a rectangular prism is:

$A=2(wl+hl+hw)$

So just plug in the values.

Height= 4

Width=2

Length=5

$A=2((2)(5)+(4)(5)+(4)(2))\\A=2(10+20+8)\\A=2(38)\\A=76m^2$

Joe is using the function E= 1.89x + 2.89y to minimize his expenses when selling

stepan [7]

Answer:

$(d)\ \$13.34$

Step-by-step explanation:

Given

$E = 1.89x + 2.89y$ -- Objective function

Constraints:

$2x + y > 10$

$x + 2y > 8$

$x,y>0$

Required

Minimum value of E

To do this, we apply graphical method

See attachment for plots of $2x + y > 10$ and $x + 2y > 8$

From the attached plot, the point that satisfy $x,y>0$ is:

$(x,y) = (4,2)$

So, we have:

$E = 1.89x + 2.89y$

This gives:

$E =1.89 * 4 + 2.89 * 2$

$E =7.56 + 5.78$

$E =13.34$

What is a simpler form of the following expressions?

nadezda [96]

Answer:

D. 49p² - 64

Step-by-step explanation:

(7p - 8)(7p + 8)

Solving this requires the 'difference of squares' concept which states;

If (a - b)(a + b)

Then the solution must be a² - b²

Considering (7p - 8)(7p + 8) then the answer is;

(7p)² - 8² = 49p² - 64
